Phoenix Equipment has for sale this world class, 17,500 BPD Cat Naphtha Sulfur Removing Unit. This unit was designed to upgrade FCC naphtha by catalytically hydrogenating sulfur compounds in the feed to form H2S in order to meet sulfur specifications. The primary sulfur hydrogenation reaction is the breaking of the carbon-sulfur bond and the subsequent reaction of the sulfur with hydrogen to produce H2S. The sulfur compounds in FCC product can be classified as mercaptans, sulfides, disulfides, or thiophenics. Mercaptans, sulfides, and disulfides are converted relatively quickly, while the thiophenics require more severe conditions.
